 ## Description
 
-TODO
+mapr is a portable and performant vector maps renderer. We aim to support the web, mobile and desktop applications. This
+is achieved by the novel [WebGPU](https://www.w3.org/TR/webgpu/) specification. Plenty of native implementations are
+already implementing this specification. On the web it is implemented by Firefox, Chrome and Safari. There are also
+standalone implementations which directly use Vulkan, OpenGL or Metal as a backend. Those backends allow mapr to run on
+mobile and desktop applications.
 
+Rust is used as a Lingua-franka on all platforms. This is made possible by WebAssembly which allows us to use Rust for
+web development.
 
-## Features
+The goal of mapr is to render maps in order to visualize data. Right now the goal of mapr is not to replace existing
+vector map renderers like Google Maps, Apple Maps or MapLibre. The current implementation serves as a proof-of-concept
+of the used technology stack. It is unclear whether the high-performance requirements of rendering maps using vector
+graphics are achievable using the current stack.

+# Building on various Platforms
+
+## Desktop (Linux)
+
+The setup normal desktop is very simple. You just have to run the following:
+
+```bash
+cargo run --bin mapr --
+```
+
+## Android
+
+First you have to install cargo-apk:
+
+```bash
+cargo install cargo-apk
+```
+
+Next, you should make sure that a recent Android NDK is installed. You will need to set the `ANDROID_NDK_ROOT` variable
+to something like this:
+
+```bash
+export ANDROID_NDK_ROOT=$HOME/android-sdk/ndk/23.1.7779620/
+```
+
+After that you can run the app on a connected device using:
+
+``bash
+cargo apk run --lib
+``
+
+## iOS
+
+In order to run this app on iOS you have to open the Xcode project at `./apple/mapr/mapr.xcodeproj`.
+You can then run the app on an iOS Simulator or a real device. During the Xcode build process cargo is used to build
+a static library for the required architecture.
+
+## Desktop (macOS)
+
+In order to run this app on macOS you have to open the Xcode project at `./apple/mapr/mapr.xcodeproj`.
+You can then run the app on a macOS. During the Xcode build process cargo is used to build
+a static library for the required architecture.
+
+*Hint: Right now only arm64/aarch64 devices are supported*
+
+## Web (WebGL, WebGPU)
+
+If you have a browser which already supports a recent version of the WebGPU specification then you can start a
+development server using the following commands.
+
+```bash
+cd web
+npm run start
+```
+
+If you want to run mapr with WebGL which is supported on every major browser, then you have to use the following
+command.
+
+```bash
+npm run webgl-start
+```
